Page 20 SH-HC30 Height Controller System Manual Page 21 5. Operating Guide After turn-on, the height controller has three states: manual, automatic and parameter editing states. 5.1 Parameter Setting In the manual or automatic mode, press the key “Enter” for a long time, enter the parameter editing state. Click the key “Enter” in the editing state, you can exit to the manual or automatic state. The exited state depends on the state before entering. In the editing state, press the function key, switch the edited parameters circularly. The switching sequence is: H (upper limit value) L ( → lower limit value) A (set value of height) E (dead → → -zone value) d (speed regulating zone value) C (detector mode selection) b (non → → → -board reduction parameters) H (upper limit value). (See 7.3) →
Click the up arrow, the selected parameter value plus 1 (for the selective range of parameter values see 7.1).
Click the down arrow, the selected parameter value minus 1 (for the selective range of parameter values see 7.1).
Manual / automatic signals: at high level, the controller is in manual state. Manual rise signal: at high level, invalid; at low level, the cutting head rises. Manual fall signal: at high level, invalid; at low level, the cutting head falls. Press the key " " on the operation ↑ panel, the cutting head rises. Press the key " " on the operation panel, the cutting head falls. ↓
When the manual rising and falling is implemented, the set value of height is modified.
Manual / automatic signal: at low level, the controller is in the automatic state. In the automatic state, the controller controls the cutting head automatically according to the set height by the user. Press the key " " on the operation panel; the set value of height plus 1; h ↑ old it, plus 1 continuously. Press the key“ ” on the operation panel; the set value of height minus 1; ↓ hold it, minus 1 continuously. 6. Debugging 6.1 Initial debugging of capacitive detection The capacitance height measurement is to detect the distance through the capacitance between the capacitance detection ring and the cutting board, namely, the height measurement mode, thereby to achieve the height control. SH-HC30 Height Controller System Manual Page 22 When the capacitive height measurement is adopted, the specific inductive capacity (SIC) between the capacitance detection ring and the cutting board may affect the height measurement accuracy due to the temperature, pressure, humidity, gas composition and many other factors on site. In addition, the serious non-linear relationship exists between the capacitance value and the height value. Our company has developed the intelligent program of "a key height calibration ". On site you only need to press a key, you can set various change factors automatically on site and realize the display and control of high accuracy, high precision and high linearity within 3-30mm. In the following situations, the height calibration is needed. 1. When the equipment is used for the first time; 2. When the use environment of equipment changes; 3. When you find that the actual height of capacitance detection ring is not consistent with its display height. Because "a key height calibration" is very simple, you only need to press a key, the users may calibrate at any time.
Check: the circular ring at the bottom of capacitance detection ring must be parallel to the cutting board. Turn on the cutting torch height controller. Set the detector mode as the capacitance detector mode (for the method see 7.3). In manual mode, the cutting nozzle is adjusted to be connected with the cutting board. Press the key "down arrow" on the height control panel for about two seconds "; a key height calibration” starts automatically, as follows: 1.Rise to about 30mm high in five steps; 2. And then fall to about 10mm from the cutting board and stop; 3. All the calibration is completed. The initial debugging is finished. For the height control operation see 5.2 and5.3. 7. Controller Panel There are display and keys on the height controller panel. Through the panel operation, you can modify relevant parameters and monitor operation status.
Set value (A: Accuracy Height): the expectation value of the space (height) between the cutting nozzle and the cutting board, set by the user. For the set range and factory value see Table 7-1. Dead zone value (E: Error Area): When the actual height is A ± E, the cutting torch height is not adjusted any more (see 1.4). For the set range and factory value see Table 7-1 Speed regulating zone (d: Down Speed Area): the speed regulating zone is between AEd ~ AE, and A
+ E ~ A + E + d (see 1.4). For the set range and factory value see Table 7-1. High limit place (H: High Limit): When the cutting torch position is higher than the set value, display alarm, and moving-up stops. For the set range and factory value see Table 7-1. Low limit place (L: Low Limit): When the cutting torch is lower than the set value, display alarm, and moving-down stops. For the set range and factory value see Table 7-1.
SH-HC30 Height Controller System Manual Selection of detector (C: capacitance): 0 is the arc voltage detection; 1 is capacitive detection. For the set range and factory value see Table 7-1. No board drop parameter (b): In the capacitive detection mode, when the detected height is higher than value b, the cutting torch stops; when the height returns to the value below it, the automatic height control continues; In the arc voltage detection mode, when it falls manually, it encounters the zero signal, the cutting torch rises to b mm in the opposite direction. For the set range and factory value see Table 7-1.

SH-HC30 Height Controller System Manual Page 26 9. Description of initial positioning function 9.1 Positioning mode The impact position switch is set in the height controller. When the cutting gun moves down and collides with the cut workpiece, the internal switch is turned on without the need of special cutting gun and "protection cap". Electrical loop must not be formed between the "protection cap" and the workpiece. This approach applies to any plasma cutting gun. How to use the positioning function: in the plasma mode, the signal of "manual down" of the external control interface is valid. When the cutting gun moves down and collides with the steel plate, the internal switch is turned on. It returns up to a certain height by automatic control of the height controller, and then positioning is completed.
Parameter value B is the positioning height, unit: mm; note when detection collision occurs, overmuch walking and certain deformation of workpieces and cantilever occur, so value B is generally set within 5-12mm. 9.3 Process This function does not require additional relevant processes and instructions by the numerical control system. It only needs to extend the time for falling of the cutting gun. Generally, the time for the falling of the cutting gun is longer than its rise; 2-6 seconds are OK. Before NC implements the perforating process, the cutting gun will rise or fall. Because the falling time will be longer than that of rise, and then the cutting nozzle may collide with the workpiece, at this time, the height controller can detect the collided workpiece and will return up to a certain distance immediately, thus the initial positioning is realized. Note even if the falling signal for the cutting gun has not been removed by NC system, the cutting torch will not continue to fall, waiting for falling delay of the cutting gun of NC to end. Why special attention should be paid to the collection of arc voltage? Because even the plasma power of different manufacturers cuts in the same environment, the arc column voltage is not necessarily the same. Fill in parameters A with the test results (see control parameters 7.1). If the value A is not tested, the current value is smaller than the current actual voltage for plasma power cutting, then the plasma cutting gun will fall rapidly until it collides with the workpiece in automatic cutting, if not, it will always rise until the arc breaks. For the new plasma power that is newly used and is not familiar, when it is equipped with the height controller for the first time, the actual starting arc testing must be made for the actual arc voltage of the plasma power supply. The normative power supply may be based on the "cutting speed chart" provided by the supporting instruction book by plasma power supply. Simple test method: adjust the distance of the cutting torch and steel plate to the appropriate value manually (according to the power process requirements). In the
SH-HC30 Height Controller System Manual Page 27 manual mode of plasma, the height controller carries out the manual starting arc perforation, after perforation, the cutting gun moves (through the numerical control system ) for actual cutting, at this time, the value on the nixie tube display of the height controller is the actual arc voltage of the plasma power supply in the current environment.

If the gas (acetylene) valve is not opened, then open gas (acetylene) for ignition; 2. The cutting gun falls (cutting gun fall delays, see M71); 3. Open the preheating oxygen valve, the preheating delay starts. If the preheating time is not enough, you can press the key【pause】, the preheating time is extended to 150 seconds automatically. If the preheating has been completed, press the key 【start】to end the preheating delay, and the preheating time is saved automatically in the preheating delay parameter; 4. The cutting gun rises(perforation cutting gun rise delay, M72); 5. Open the cutting oxygen valve (M12), perforation delay time is delayed, after that the cutting gun falls (perforation cutting gun falling delay M73); 6. Turn on the height controller (M38); the following procedures start.
1. The cutting gun falls (the falling of cutting gun delays, see M71); 2. If the selected perforation positioning is valid, then the cutting gun falls until it collides with the lower limit position switch, thus the falling stops; the cutting gun rises, after perforation positioning delay is delayed, the cutting gun stops; 3.Turn on the starting arc switch; 4. Detect the signal of "arc voltage success", if the arc voltage detection selects 0 in the setting of parameters (not detected), the arc voltage is not detected. After starting arc succeeds, the perforation delay is delayed (seconds) 5. Turn on the height controller (M38); the following procedures start.
SH-HC30 Height Controller System Manual Page 28 M08 1. Close the cutting oxygen (M13); 2. Turn off the height controller (M39); 3. The cutting gun rises (M70); The plasma cutting operation sequence is as follows: M08 1. Turn off the arc voltage switch; 2. Turn off the height controller (M39); 3. The cutting gun rises (M70). M50 perforation action: 1. The cutting gun rises (M72); when the plasma operation is carried out, there is no such action; 2. Open the cutting oxygen (M12); or plasma starting arc starts and the signal of "arc voltage success" is detected. 3. The cutting gun falls (M73), when the plasma operation is carried out, there is no such action; 4. Turn on the height controller (M38) M70 Fixed cycle of the cutting gun rise: It is used when the procedure starts and the cutting procedure of a stage ends, the cutting gun is lifted so that it can move to the next cutting position quickly. Operation sequence: turn on the cutting gun rise switch (M14), cutting gun rise delay is delayed; turn off the switch for the cutting gun rise (M15). M71 Fixed cycle of cutting gun fall: It is used before perforation. Its action is contrary to M70, but the value is smaller, because of the action of gravity, falling is faster than rising. Operation sequence: turn on the switch of cutting gun fall (M16), cutting gun fall delay is delayed, turn off the switch of the cutting gun fall (M17). M72 Perforation cutting gun rise cycle: It is used after preheating. The cutting gun is lifted to a certain extent. Avoid that sprayed steel slag blocks the muzzle of the cutting gun when the cutting oxygen is opened. Operation sequence: turn on the switch of the cutting gun rise (M14); perforation cutting gun rise delay is delayed; turn off the switch of cutting gun rise (M15).
It is used after the preheating. After the implementation of M72, open the cutting oxygen, the cutting gun is placed in the cutting position, the reverse action of M72, but the value is smaller. Because of the action of gravity, falling is faster than rising. Operation sequence: turn on the switch of the cutting gun (M16); the perforation cutting gun delay is delayed; turn off the switch of the cutting gun (M17). M75 Cutting gun positioning delay: When the plasma gun is positioned, first the cutting gun falls (M16), when it comes to the lower limit place (see the input port XXW 8), the falling of the cutting gun stops (M17). Then, the cutting gun rise is started (M14); after the cutting gun positioning delay, the rising of the cutting gun stops (M15); 11. Height Adjustment Remote Controller In order to make the users be far away from the cutting site in operation, and make them use it easily, simply and intuitively, our company provides the users with the dedicated remote controller, as shown in Figure X-1. SH-HC30 Height Controller System Manual
The remote controller uses the computer core design and can implement the information communication RS232 with the master controller. The adjustment of the height and the sensitivity adopts the simple knob design so that it has the operation conveniences of analog circuit and accuracy and reliability of digital circuit. Graphic model of remote controller Figure X‐1 Outside view of the height adjustment remote controller
3 indicator lights. Power: when the light is on, it is in the electrifying state. Manual: when the light is on, it is in the manual operation state, at this time the automatic indicator light is off. Automatic: when the light is on, it is in the automatic operation state, at this time the manual indicator light is off. 3 buttons. Manual/ automatic: switching between the manual and automatic state. Rise: the cutting torch rises manually. Fall: the cutting torch falls manually. 2 knobs, as shown in Figure X-2. Height: in automatic state, the height of cutting torch is adjusted. Sensitivity: in automatic state, the control sensitivity of the cutting torch is adjusted.
Page 29 SH-HC30 Height Controller System Manual When it is powered on, the controller is in manual operation state, the indicator light "Manual" is on, while the indicator light "automatic” is off. At this time, if the height of the cutting torch needs to be adjusted, the button of "up" or "down" may be pressed. When you press the key “up”, the cutting torch rises; when you stop pressing, rising stops. In the same way, press the button of "down", the falling of the cutting torch may be completed. When the automatic height control is needed, click the button of "manual /automatic", the light of "Manual" is off; the light of "Automatic" is on, which makes the height controller enter the automatic control mode. In this mode, the height of the cutting torch is adjusted according to the set height automatically.
controller, namely, direct external switch control mode and the remote controller control mode. In this system, if two external control modes exist simultaneously, only when the two modes are in the automatic control state, the height controller may enter the automatic control state, otherwise, they are manual control states. If the height does not meet the requirements, regulate the knob of "height" to set. 0% is low, 100% is high. If you think the regulation accuracy is not enough, you can adjust the knob of "sensitivity" to the low position (direction 0%), thereby the sensitivity is improved, but it should not be too low, otherwise it may cause the cutting torch oscillate up and down; When oscillation is found, the knob of "sensitivity" can be adjusted to a high position (direction 100%) till the oscillation is eliminated, which is the best. 11.3 Wiring Instructions Wiring diagram is shown in Figure X-3.
